    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • Ffmpeg stream rtsp via h264 with low quality

    9 novembre 2017, par dscsdc

    When i stream rtsp with ffmpeg via upd i got lot of errors of error while decoding MB 48 31, bytestream. and i see the video with low quality.

    I stream with ffmpeg according to this command :ffmpeg -i rtsp://x.x.x.x/... http://y.y.y.y:zzzz

    On this way I send the data to ffserver and then I can watch the video via ffplay or vlc according to url :rtsp://w.w.w.w:(port)/live.h264
    (I have ffserve conf that stream to h264 file).

    When i stream via rtsp tcp all is fine, and i see the video well. but when i stream with rtsp udp i got video with very low quality, freezes or gets stuck.

    I want to understand 2 stuff :

    1. I know that udp is less reliability then tcp, but when i watch on stream from another streaming via rtsp udp i see the video with much more quality.
      is ffmpeg has a problem to stream udp or is that because i stream h264 with rtsp udp.
      What can i do to improve performance of ffmpeg with rtsp udp ?

    2. What does it matter witch type of file i stream (on rtsp udp) if this will be h264 or avi or mp4 or ffm or amp ?
      i see lot of streaming that stream amp , and another that streaming h264

  • How to get Continuous live streaming without buffering in azure media player using FFMPEG(Latency is not a issue) ?

    29 août 2019, par vinay

    I am streaming from the ip camera which uses RTSP protocol and ingesting the feed to RTMP(to Azure media server) using the following command

    ffmpeg command : ffmpeg -f lavfi -i anullsrc -rtsp_transport tcp -i rtsp ://CloudAppUser:admin@192.168.8.145/MediaInput/h264/stream_1 -vcodec libx264 -t 12:00:00 -pix_fmt + -c:v copy -c:a aac -strict experimental -f flv rtmp ://channel1-cloudstream-inso.channel.media.azure.net:1934/live/980b582afc12e421b85b4jifd8e8662b/df

    I am able to watch the stream but it is buffering once in every 30 seconds , and I want to know the reason behind this buffering

    Please any one change this command , so that it should not buffer

    I am executing this command from my terminal

    I would like to watch my live stream in azure media player without any buffering and latency below 1 minute is not an issue

  • ffmpeg showwaves - Change color of waveform on top of an image

    15 août 2020, par Grant SYNKOP

    I need help with ffmpeg.

    



    I wrote this code :

    



    @echo off  
for %%F in (*.opus *.ogg) do 
(  
  ffmpeg -y -i "%%F" -loop 1 -i "default.jpg" -filter_complex " 
 [0:a]showwaves=s=2560x1440:mode=cline:r=30,colorkey=0x000000:0.01:0.1,format=yuva420p[v];
[1:v][v]overlay[outv]" -map "[outv]" -pix_fmt yuv420p -map 0:a -vcodec libvpx-vp9 -lossless 1 -speed 8 -acodec copy -shortest "%%~nF.webm" 
)


    



    What it does is that for each .opus or .ogg audio file, it'll output a video with a default.jpg background image (which is completely white) and a waveform on top of it, with the audio playing.
Problem is, I would change the color of the waveform to black, but I don't understand how colorkey works even after reading the documentation...

    



    Basically, I want to obtain something like this (but the waveform being in black) : https://www.youtube.com/watch?v=k9arneFijG8

    



    Thanks in advance.
